The Mighty Wallet is tear-resistant, water-resistant, expandable and recyclable. Made from Tyvek, these cool wallets resist tearing because of thousands of interlocking plastic fibers spun in random patterns, giving them incredible strength. The ingenious origami construction was and is the original folded Tyvek wallet designed by Terrence Kelleman. The stitch less design reinforces the materials own strength and allows these very slim wallets to instantly expand and adapt to your own personal storage needs. Choose from seven new DC Comics styles - All-American Superman, Batman Mask, Catwoman, The Joker's Last Laugh, Harley Quinn: Harley Card, Woman Woman: Standing Strong, or the Justice League.
